It’s ideal for keeping things lightweight and readable—both for you and your customers.

Hyperline supports markdown formatting **in select text areas** across the product: * Invoice legal information * Invoice additional information Currently, formatting is visible only in preview mode. While editing, the Markdown syntax remains visible in the input field. You can use the following syntax to apply formatting: * `**text**` -> bold text * `*text*` or `_text_` -> italic text * `---` -> horizontal divider * `- text` -> bulleted list * `[text](http://www.hyperline.co)` -> hyperlink ## Variables We support dynamic content rendering using variable substitution. Variables can be embedded directly into input fields using two common formats: * Double curly braces: `{{variable}}` * Single curly brace: `{variable}` These placeholders are automatically replaced at runtime with the appropriate values from the corresponding data context (e.g., quote, invoice, customer, ...). You can create you own variables via [custom properties](https://docs.hyperline.co/docs/properties/overview). The variable is the slug of the custom property, surrounded by curly brackets.
